Rinse cauliflower and cut into smaller florets. Put this in a food processor and pulse until you get a fine texture, resembling rice.
In a frying pan on low heat, add heavy cream, butter, lemon juice, and onion powder. Stir together.
Add cauliflower to the pan and simmer for 10-15 minutes, stirring often. Add salt and pepper to taste.
Once the cauliflower starts to get tender, stir in the parmesan cheese.
Once the cheese is incorporated, stir in the spinach.
Plate and serve with goat cheese and walnuts.
